Usage Guidelines

Usage Scenario

The MAC address table of a switch stores MAC addresses of other devices. The switch queries the MAC address table to quickly locate the outbound interface for data forwarding. You can run the display mac-address bridge-domain command to view MAC address entries of a specified BD.

Follow-up Procedure

If any MAC address entry in the command output is incorrect, run the undo mac-address command to delete the entry or run the mac-address static command to add a correct one.
